Tunneling in weak Rocks by Singh and Goel

 This book by Bhawani Singh and Rajnish K. Goel is a very easy to read and useful book for the students of the UG and PG courses of Geo-technical Engineering. I got this book from my course teacher, and it is very helpful.

In this post, I want to share with you the quotes those are written in the book, at the bottom of every title line at the start of the new chapter.
I loved these quotes, and they somehow motivated me to read this book.

1. (Chapter No.1 INTRODUCTION)
"College is where you learn how to learn" - Socrates (470 - 399 B.C.)

2. (Chapter No.2  Applications of Geophysics in tunneling and site survey activities)
"And so Geology once considered mostly a descriptive and historical science has in recent years taken on the aspect of an applied science. Instead of being largely speculative as perhaps it used to be, geology has become factual, quantitative, and immensely practical. It became so first in mining as an aid in the search for metals; then in the recovery of fuels and the search for the oil; and now in engineering in the search for the more perfect adjustment of man's structure to nature's limitations and for greater safety in public works." -  Charles P. Berkey, Pioneer Engineering Geologist. 

3. (Chapter No.3 Terzaghi's Rock Load Theory)
"The Geological engineer should apply theory experimentation but temper them by putting them into the context of the uncertainty of nature. Judgement enters through engineering." - Karl Terzaghi

4. (Chapter No.4 Rock Mass Rating (RMR))
"Effectiveness of knowledge through research(E) is E = mc^2; where m is the mass of knowledge and c is communication of knowledge by publications."   - Z.T. Bieniawski

5. (Chapter No.5  Rock Mass Quality Q)
"Genius is 99 percent perspiration and 1 percent inspiration." - Bernard Shaw

6. (Chapter No.6  Rock Mass Number)
 " My attention is now entirely concentrated on rock mechanics, where my experience in applied soil mechanics can render useful services. I am more and more amazed about the blind optimism with which the younger generation invades this field, without paying any attention to the inevitable uncertainties in the data on which their theoretical reasoning is based and without making serious attempts to evaluate the resulting errors."     - Annual summary in Terzaghi's Diary

7. (Chapter No.7 Strength of Discontinuities)
"Failure is success if we learn from it."  - Malcom S. Forbes

8.(Chapter No.8 Strength enhancement of rock mass in tunnels)
 "The behaviour of microscopic systems is generally described by non linear laws. (The non-linear laws may explain irreversible phenomena like instabilities, dualism, unevolving societies, cycles of growth and decay of societies. The linear laws are only linear approximation of the non-linear laws at a point in time and space.)"    -  Ilya Prigogine, Nobel Laureate

In this book,  there are 29 chapters in total, I think it would be a length post to write all of the quotes in one post, let me know if you want the others. If you want to buy the book, go to the Amazon link I have given above.
